    Update on rear wheels. Confirmed! The hub contact is insufficient to provide proper centering on the outer wheel. Also, the inner alloys need to be warm to R&I from the hub without drama.

    171" is the Wheelbase I have measured. It is a factory cab conversion from 2 to 4 door. Any frame changes would be from GM.
